Out of curiosity more than anything else, I was just wondering if there would be any benefits to be gained by fitting modern valve guide seals to an Austin Seven engine?
These greatly improve the BMC overhead valve A, B and C series engines which had rudimentary valve guide seals in the form of little fat O-rings which didn't seam to do much of anything.
Given that the valves and guides hang down on the Seven as opposed to being the other way up in the head, perhaps they don't require seals because gravity helps keep oil from being drawn into the guide and valve stem?
Your thoughts?
Cheers,
Stephen
